12 Claims. (Cl. 268104) This invention relates to a ventilator assembly and relates particularly to a ventilator assembly for the type of ventilator which projects outwardly to open. The in vention relates still more particularly to a ventilator assembly of the type having a pivotal rigid actuator arm for movement of the ventilator. However, the invention is not so limited in that it may be used with other types of ventilators and may be employed with other kinds of apparatus.

In the past problems have existed concerning the guides and supports for the projecting type of ventilator. One of the problems has been in regard to the installation of the guides and supports. In order to operate a venti lator which projects outwardly to open, it has been custornary to attach an elongate channel guide member to the ventilator by means of a plurality of aligned hinge members. However, the attachment of the numerous hinge members to the ventilator in proper positions has been very difiicult. Another problem related to the projecting type of ventilator has been in the disconnection of the ventilator from the actuator so that the ventilator could be pivotally moved within its frame to a positionfor cleaning of both sides of the ventilator.

Another problem related to the projecting type of ventilator assembly has been in regard to attachment of an actuator to the ventilator wherein connection of the actuator to the frame and to the ventilator could be easily accomplished during installation. In order to obtain ease of installation, it was necessary to permit objectionable looseness among the elements and thus wind and breeze could cause considerable vibratory or shaking movement of the ventilator in adjusted open position.

Hence, an object of this invention is to provide a ventilator assembly adapted for use with a projecting type of ventilator, which assembly is easily and readily attachable to a ventilator and which assembly firmly retains the ventilator in any adjusted position.

Another object of the invention is to provide a ventilator assembly having means for easy and rapid disconnection of a ventilator actuator from a ventilator for manual movement beyond the limits of the actuator. For example, for movement to an extreme open position so that both sides of the ventilator may be cleaned by a person located within the room.

Another object of the invention is to provide a combination slide shoe and hinge for a ventilator assembly.

Another object of this invention is the provision of a two-way hinge, the hinge having means for pivotal operation about two axes, each axis being normal to the other axis.

Another object of the invention is the provision of a combination clevis and hinge device.

Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

Referring to the drawings in detail, the ventilator assembly as shown in Figure 1 comprises a ventilator 20 attached to a ventilator frame 22 by means of a pivotally connected support bar 24. A support channel 26 attachednear the upper portion of the ventilator frame 22 aids in directing movement of the ventilator 20. The ventilator 20 is adapted to be adjusted by means of a pair of operator arms 28 which are attached to a ventilator operator 30 provided with an operator handle 32.

A guide channel 34 is firmly attached to the ventilator 20 by means of a plurality of screw or bolt members 36. At the end of each operator arm 28 is a combination bracket and clevis assembly 37 attached in the manner shown in Figures 2, 3, 4, 5 and 6. Each bracket and clevis assembly 37 comprises a slide shoe or connector bracket 38 which is provided with a pair of elongate substantially fiat portions 40 joined by a pair of aligned spaced apart arcuate portions 42, as best shown in Figures 2 and 3. The flat portions 40 of the slide shoe 33 are adapted to slidably move within bent-over lip portions 44 of the guide channel 34, as clearly shown in Figure 4.

Attached to the slide shoe 38 intermediate the'arcuate portions 42 and disposed adjacent the guide channel 34 is a curved bearing 59, as clearly shown in Figure 4. Also disposed intermediate the two arcuate portions 42 of the slide shoe 38 is a clevis or connector link 52 comprising an arcuate portion 53 joining a pair of flat leg or leaf portions 54 and 56. Herein the leg portion 54 is shown as the uppermost.

The arcuate portion 53 0f the clevis 52 is held in engagement with the curved bearing 50 by a pivot pin 69 which is substantially the length of the slide shoe 38. The pivot pin 60 engages the arcuate portion 53 of the clevis 52 and engages the arcuate portion 42 of the slide shoe 38. and thereby interlocks the clevis 52 and. the slide shoe 38. Thus, the. pivot pin 60 connects the slide shoe 38 to the clevis 52, and the bearing 50 positions the arcuate portion 53 within the slide shoe 38. A small portion of the extreme end of .the arcuate portions 42 of the slide shoe 38 is bent inwardly, as shown by reference numeral 64, for the purpose of retaining the pin 60 against longitudinal movement with respect to the slide shoe 38.

Extending inter-mediate the legs 54 and 56 of the clevis 52 and normal thereto is a pintle or rivet '66. Rotatably encompassing the pintle 66 is a key 68. The key 68 extends between the two legs 54 and 56 of the clevis 52 and is provided with a pair of opposed arcuate peripheral edges 70 and a pair of opposed flat parallel surfaces or side portions 72, as clearly shown in Figures and 6.

Rigidly attached to the key 68 adjacent the leg 54 of the clevis 52 is an elongate spring plate or lever 74. The spring plate 74 is rotatable with the key 68 and serves as a lever member for the key 68.

The end of each operator arm 28 is provided with a key slot 7 8. The key slot 78 is defined by a pair of flat side entrance portions 80 leading to an internal arcuate portion 82.

When it is desired to attach the slide shoe and clevis assembly to one of the operator arm members 28, the elongate spring plate 74 is rotatably positioned, as shown in Figure 3, with the longitudinal axis of the spring plate 74 substantially parallel with the longitudinal axis of the slide shoe 38. With the spring plate 74 thus positioned, the key 68 is rotatably positioned so that the flat side portions 72 of the key 68 are parallel to the flat side entrance portions 80 of the key slot 78. The distance between the side portions 72 of the key 68 is slightly less than the distance between the fiat side entrance portions 80 of the key slot 78. Thus, the key 68 may slide through the flat side entrance portions 80 of the key slot 78 to be positioned within the arcuate portion 82 of the key slot 78.

The radius of curvature of the arcuate portion 82 of the key slot 78 is slightly larger than the radius of curvature of the arcuate peripheral edges 70 of the key 68. Therefore, the key 68 may be rotated within the arcuate portion 82 of the key slot 78. Thus, after the key 68 is disposed within the arcuate portion 82 of the key slot 78, the elongate spring plate 74 is rotated toward the operator arm 28.

The spring plate 74 is provided with a pair of cars 84 extending normal to the surface of the plate 74. The spring plate 74 may be bent outwardly from the arms 28, as shown in Figure 4, to permit the ears 84 to move over the operator arm 28 during rotation of the spring plate 74, actuating rotation of the key 68 within the key slot 78.

Thus, the spring plate 74 may be positioned so that the cars 84 thereof engage the edges of the operator arm 28, as shown in Figure 2. When the elongate spring plate 74 is rotated from the position shown in Figure 3 to the position shown in Figures 2 and 4, which is a rotative movement of approximately 90 degrees, the key 68 is naturally also rotated through approximately 90 degrees so that the arcuate edges 70 of the key 68 slidably engage the arcuate portion 82 of the key slot 78, and the flat side portions 72 of the key 68 are disposed normal to the longitudinal axis of the arm 28, as clearly shown in Figures S and 6. The spring plate 74 is thus positioned in locking engagement with the operator arm 28, as shown in Figures 2 and 4, while the key 68 is locked within the key slot 78.

With the clevis 52 so attached to the operator arm 28, the slide shoe 38 slidably moves within the'channel 34 during adjustment of the ventilator by means of the operator arm 28. Rotative movement of the key 68 about'the pintle 66 permits pivotal movement of the arm 28 withrespect to the clevis 52. Furthermore, the connection of the clevis 52 to the slide shoe 38 by means of the pin 60 permits pivotal movement of the clevis 52 4 with respect to the slide shoe 38, as the arcuate portion 53 of the clevis 52 engages the bearing 50. Thus, the ventilator 20 is readily adjusted by means of the ventilator operator 30 and the arms 28. With these pivotal connections, the ventilator 20 is firmly retained in any adjusted position.

When it is desired to move the ventilator 20, shown in Figure 1, to a horizontal or substantially horizontal po sition for cleaning of the outer side of the ventilator 20, it is necessary to detach the ventilator 20 from the operator arm 28. This disconnection may be easily accomplished by lifting the end of each spring plate 74 from engagement with its respective operator arm 28, as shown in Figure 4, in order to provide clearance for movement of the cars 84 over the surface of the arms 28. The spring plate 74 is then rotated with respect to the. clevis 52, thus rotating the key 68 within the key slot 78 so that the side portions 72 of the key 68 become parallel with the entrance portions of the key slot 78. The key 68 may then be moved from the key slot 78 by passing through the entrance portions 80 of the key slot 78. Thus, each clevis 52 is disconnected from its respective arm 28. The slide shoes 38 remain within the guide channel 34.

Figure 3 shows the clevis 52 detached from connection with the arm 28. The ventilator 20 may then be pivotally moved to any desired position for cleaning of the outer surface thereof. After this cleaning operation is completed, the ventilator'20 is then returned to a position in which the clevises 52 are adjacent the ends of their respective arm members 28 so that attachment of the clevises 52 to the arm members 28 may again be readily accomplished, as described above.

In Figures 7 and 8 is shown a modification of the connection means of the ventilator assembly of this invention., In this modification is a slide shoe slidably positioned within a guide channel 91 similar to the guide channel 34. The slide shoe 90 is provided with a centrally located arcuate bearing 92. The guide channel 91 is secured to a ventilator 93 by means of bolts or screws 94. Pivotally attached to the slide shoe 90 by means of a pin 95 is a clevis 96. The clevis 96 has an arcuate portion 97 which is adapted to engage the arcuate bearing 92 of the slide shoe 90. Thus, pivotal movement of the clevis 96 is guided by the arcuate bearing 92 of the slide shoe 90. The clevis 96 is pivotally attached to an operator arm 98 by means of a screw 100 provided with a head 102.

Thus, the slide shoe 90 is slidable within the guide channel .91 and is pivotally movable with respect to the clevis 96; the clevis 96 is pivotally movable with respect to the operator arm 98. Thus, the ventilator 93 may be readily adjusted by. means of the operator arm 98.

When it is desired to detach the ventilator 93 from the operator arm 98, all that is necessary is to remove the screw 100, thus detaching the clevis 96 from the arm 98 so that the ventilator 93 may be pivotally moved to a more extreme position than that permitted by the actuator arm 98.

In Figures 9, 10 and 11 is shown another modification of the connection means of a ventilator assembly of this invention. In this modification a slide shoe 104 is pivotally attached to a clevis 105 by means of a pin 106. The slide shoe 104 is provided with a centrally located arcuate bearing 107, shown in Figure 11. The clevis 105 has an arcuate portion 108 joining a pair of parallel legs or leaves 109. The arcuate portion 108 is adapted to engage the bearing 107 of-the slide shoe 104 during pivotal movement of the clevis 105. Extending through the leaves 109 of the clevis 105 normal thereto is a hollow bushing 110. I r

The clevis 105 is adapted to be attached to an operator arm 112 which is provided with .a slot 114 in the end thereof, as clearly shown in- Figure 9. Pivotally attached to the operator arm 112 by means of a connector pivot pin 116 is a spring plate 118. The spring plate 1I8 has'a bent portion 119' joining an end portion 120. Within the end portion 120 is a locking pin 122 normal thereto. The spring plate 118 may be bent upwardly and outwardly from the arm 112, as shown in Figure 11, in order to place the locking pin 122 within the hollow bushing 110. Thus, the clevis 105 is attached to the operator arm 112, as clearly shown in Figures and 11.

It is understood from the above description that the ventilator assembly of this invention provides means by which a ventilator may be readily, easily and quickly attached to an operator arm. The invention also provides means by which the operator arm may firmly retain a ventilator in any adjusted position. A ventilator retained by the assembly of this invention may be easily adjusted by an operator arm. The ventilator may be quickly and easily disconnected from an operator arm by use of the assembly of this invention.
